Check eBay. Though I don’t recommend getting shipped eggs. I’ve bought two sets of fertile eggs from two different breeders online and none were fertile. Check Preloved for anyone selling fertile eggs near you.
Hi - I second eBay - I've also bought 2 sets of eggs from eBay - my first batch didn't hatch but my hen was sitting during those awful rainstorms we had a few months ago so I would say the humidity was way too high - I cracked the eggs when they had passed viability and they had almost made it!!! my second batch I bought a dozen ( guessing a 50% max hatch rate ) and we got 7 chicks so success ! I also bought a 3rd lot the other day from eBay but my hen has snapped out of her broodiness so I guess I'll have to wait until spring for my next chicks good luck !!
